| 摘 要： | 合成了一系列氨基酸类离子液体,从中筛选出对溶解壳聚糖具有良好性能的离子液体——甘氨酸盐酸盐离子液体。在常温常压下考察了该离子液体1%～10%水溶液对壳聚糖的溶解能力,溶解壳聚糖能力最大能达到6.32%(质量分数,下同)。对离子液体重复使用5次后,溶解能力没有明显下降。采用X射线衍射(XRD)和红外光谱(FT-IR)对再生的壳聚糖进行表征,结果表明,壳聚糖在溶解过程中没有发生衍生化。甘氨酸盐酸盐离子液体水溶液是壳聚糖的良溶剂。

| Abstract: | A series of amino acid ionic liquids were synthesized and an ionic liquid [Gly]Cl with better dissolution performance was selected. The concentration of ionic liquid aqueous solution was investigated from 1% to 10% at normal conditions. The largest dissobulity could reach to 6.32%. The ionic liquid could be reused for 5 times without any decrease in the dissolubility. The structures of recycled chitosan were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopic(FT-IR). The re... |
